Description

Die Erfindung betrifft eine Vorrichtung zum manuellen Rücken von Baumstämmen, mit einem Werkzeugschaft und wenigstens einem an einem Schaftende des Werkzeugschaftes gehaltenen Werkzeugkopf. Solche Vorrichtungen sind zB aus CH648370 , BE391388 oder CN201248232Y bekannt.The invention relates to a device for the manual back of tree trunks, with a tool shank and at least one held on a shank end of the tool shank tool head. Such devices are for example CH648370 . BE391388 or CN201248232Y known.

Derartige Vorrichtungen werden als Sappie oder als Grießbeil bezeichnet und fungieren als manuell handhabbares Mehrzweckgerät, insbesondere als Rückenhilfe zum Rücken geernteten Holzes. Zu Zeiten der konventionellen Holzernte wurde der Werkzeugschaft aus Eschenholz oder anderen für die Herstellung von Werkzeugschäften geeigneten Holzarten gefertigt. Der geschmiedete Werkzeugkopf weist ein Auge auf, in dem der Werkzeugschaft mittels eines Keils verspannt ist. Zu Zeiten der industriellen Holzernte hat sich jedoch unter dem verstärkten Einsatz von Arbeitsmaschinen das Anforderungsprofil und damit auch das äußere Erscheinungsbild des Sappies verändert. So wird der Werkzeugschaft moderner Sappies insbesondere aus legierten Aluminiumhohlprofilen und der Werkzeugkopf aus gehärtetem Stahlblech gefertigt. Das veränderte Anforderungsprofil beinhaltet insbesondere einen maschinelle Arbeiten begleitenden oder unterstützenden Einsatz des Sappies. Dem veränderten Anforderungsprofil tragen die bekannten Sappies jedoch nicht in einem ausreichenden Maße Rechnung.Such devices are referred to as Sappie or Grießbeil and act as manually manageable multi-purpose device, especially as a back-up to the back harvested wood. At the time of conventional timber harvesting, the tool shank was made of ash wood or other types of wood suitable for the manufacture of tool shanks. The forged tool head has an eye in which the tool shank is clamped by means of a wedge. At the time of industrial timber harvesting, however, the requirement profile and thus also the external appearance of the Sappies has changed under the increased use of working machines. For example, the tool shank of modern Sappies is made of alloyed aluminum hollow profiles and the tool head is made of hardened sheet steel. The changed requirement profile includes in particular a mechanical work accompanying or supporting use of the Sappies. However, the well-known Sappies do not adequately take account of the changed requirement profile.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung aufzuzeigen, mit der dem veränderten Anforderungsprofil auf besonders einfache Weise Rechnung getragen wird.The invention is therefore based on the object to show a device of the type mentioned, with the changed requirement profile is taken into account in a particularly simple manner.

Diese Aufgabe ist erfindungsgemäß durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features of claim 1. Advantageous developments of the invention are specified in the subclaims.

Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, dass der Werkzeugkopf wenigstens zwei, in Längsrichtung des Werkzeugschaftes nebeneinander angeordnete Schleppzinken aufweist. Sind beide Schleppzinken in das Holz eines zu rückenden Baumstammes eingeschlagen, können neben den von Hand am Werkzeugschaft eingeleiteten Zugkräften auch Drehmomente auf den Baumstamm übertragen werden. Zugkräfte und Drehmomente dienen insbesondere dem Ausrichten und Positionieren des einer Maschine zuzuführenden Holzes, so dass das erfindungsgemäße Sappie für einen maschinelle Arbeiten begleitenden oder unterstützenden Einsatz besonders geeignet ist.The device according to the invention is characterized in that the tool head has at least two trailing tines arranged side by side in the longitudinal direction of the tool shank. If both trailing tines are hammered into the wood of a tree trunk to be retracted, torques can also be transmitted to the tree trunk in addition to the tensile forces introduced by hand on the tool shank. Tensile forces and torques are used in particular for aligning and positioning the wood to be supplied to a machine, so that the invention according to the invention is particularly suitable for a machine-accompanying or supporting use.

Erfindungsgemäss weist jede Schleppzinke eine krallenartig ausgeformte Zinkenspitze mit wenigstens einer auf ihrer Konkavseite ausgebildeten Zahnung auf. Diese erlaubt auch das Rücken von Schwachholz, das aufgrund seiner zu geringen Masse das Einschlagen der Zinkenspitzen schwierig oder gar unmöglich macht. Die Zahnung verhindert dabei das Abrutschen der zum Rücken hinter das Schwachholz greifenden Schleppzinken.According to the invention, each drag tine has a claw-like shaped tine tip with at least one toothing formed on its concave side. This also allows the back of weak wood, which makes the tapping of the tine tips difficult or even impossible due to its low mass. The toothing prevents the slipping of the trailing tines behind the weak wood.

Nach einer Weiterbildung der Erfindung weisen die Schleppzinken zueinander gegensinnig ausgebildete Abkröpfungen auf, wobei die einander zugekehrten Kröpfschenkel aneinander anliegend und mit wenigstens einem der Schaftenden des Werkzeugschaftes verbunden sind. Zur Verbindung des Werkzeugschaftes mit dem Werkzeugkopf weisen seine Schleppzinken im Bereich ihrer aneinander anliegenden Kröpfschenkel Einspannhälse auf, die mit dem vorzugsweise aus einem legierten Aluminium- oder Stahlhohlprofil hergestellten Werkzeugschaft fest verbunden sind.According to a development of the invention, the trailing tines have mutually oppositely formed offsets, wherein the mutually facing crimping legs are adjacent to each other and connected to at least one of the shank ends of the tool shank. To connect the tool shank with the tool head, its trailing tines have gripping necks in the region of their adjoining crimp legs, which are firmly connected to the tool shank preferably made of an alloyed aluminum or hollow steel profile.

Um die Verbindung der Einspannhälse mit dem Werkzeugschaft vor schädlichen Hebelkräften zu schützen, die aus einer Spreizung der nebeneinander angeordneten Schleppzinken resultieren, wird vorgeschlagen, die Schleppzinken an ihren aneinander anliegenden Kröpfschenkeln über wenigstens eine starre Verbindung zusammenzuhalten. Die starre Verbindung ist beispielsweise durch eine Vernietung, Verschraubung oder eine Verschweißung hergestellt.In order to protect the connection of the Einspannhälse with the tool shank from harmful leverage resulting from a spread of juxtaposed trailing tines, it is proposed to hold together the trailing tines at their abutting Kröpfschenkeln via at least one rigid connection. The rigid connection is made for example by riveting, screwing or welding.

Nach einer nächsten Weiterbildung der Erfindung weist der Werkzeugschaft wenigstens einen die Schleppzinken basisseitig umschließenden Futterkörper auf. Der Futterkörper weist die Einspannhälse der Schleppzinken im Hohlprofil des Werkzeugschaftes formschlüssig aufnehmende Klemmbacken auf, die zusammen mit den Einspannhälsen der Schleppzinken und dem Werkzeugschaft eine Steckverbindung ausbilden, die mittels Vernietungen oder Verschraubungen gegen ein Auseinanderziehen gesichert ist. Der die Schleppzinken basisseitig umschließende Teil des Futterkörpers verbindet die Klemmbacken vorzugsweise einstückig miteinander, so dass eine besonders belastungsfähige und gleichwohl geschützt angeordnete Verbindung des Werkzeugschaftes mit dem Werkzeugkopf hergestellt ist.According to a next development of the invention, the tool shank has at least one chuck body enclosing the toe tines on the base side. The chuck body has the Einspannhälse the towing tines in the hollow profile of the tool shank positively receiving jaws, which form together with the Einspannhälsen the towing tines and the tool shank a plug connection, which is secured by rivets or fittings against pulling apart. The trailing tines enclosing base part of the chuck body connects the jaws preferably in one piece with each other, so that a particularly resilient and yet protected arranged connection of the tool shank is made with the tool head.

Nach einer anderen Weiterbildung der Erfindung weist der Werkzeugschaft ein Griffteil mit wenigstens einem zwischen seiner Grifffläche und dem Werkzeugkopf ausgebildeten Fingerschutz auf. Der Fingerschutz verringert das Risiko von Verletzungen an den Fingern einer das Sappie am Griffteil ergreifenden Hand. Die griffinnenseitig an dem Fingerschutz ausgebildete Griffmulde weist einen Öffnungswinkel von wenigstens 75° auf, so dass eine mit dem erfindungsgemäßen Sappie arbeitende Person ihre Hand jederzeit gefahrlos aus der Griffmulde des Griffteiles zurückziehen kann.According to another embodiment of the invention, the tool shank has a grip part with at least one finger guard formed between its grip surface and the tool head. The finger guard reduces the risk of injury to the fingers of a hand gripping the sappie on the handle. The gripping recess formed on the inside of the finger guard has an opening angle of at least 75 ° so that a person working with the sappie according to the invention can safely withdraw his hand from the recessed grip of the gripping part at any time.

Nach einer besonders vorteilhaften Weiterbildung der Erfindung ist der Werkzeugschaft als Schiebeführung für das Griffteil ausgebildet, wobei der Schiebeführung wenigstens ein Feststellmechanismus zugeordnet ist. Damit besteht die Möglichkeit der Einstellung unterschiedlicher Schaftlängen, so dass der Einsatzbereich des erfindungsgemäßen Sappies vorteilhaft vergrößert ist. Der Feststellmechanismus weist vorzugsweise eine Rastmechanik auf, die vorzugsweise über ein federbelastetes Betätigungsorgan entriegelbar ist.According to a particularly advantageous embodiment of the invention, the tool shank is designed as a sliding guide for the handle part, wherein the Sliding guide is associated with at least one locking mechanism. This makes it possible to set different shaft lengths, so that the range of use of the invention is advantageously increased Sappies. The locking mechanism preferably has a latching mechanism, which is preferably unlocked via a spring-loaded actuator.

Um den Werkzeugschaft unter Einhaltung ergonomisch komfortabler Schaftverläufe als Schiebeführung ausbilden zu können, ist vorgesehen, dass der Werkzeugschaft wenigstens zwei gerade Schaftabschnitte aufweist, und dass die geraden Schaftabschnitte über einen wenigstens einfach gekrümmten Schaftabschnitt miteinander verbunden sind. Grundsätzlich ist es jedoch ausreichend, lediglich den die Schiebeführung für das Griffteil ausbildenden Schaftabschnitt gerade auszubilden.In order to be able to form the tool shank in compliance with ergonomically comfortable shank profiles as a sliding guide, it is provided that the tool shank has at least two straight shank sections, and that the straight shank sections are connected to one another via an at least single curved shank section. In principle, however, it is sufficient merely to form the shank section which forms the sliding guide for the grip part.

Um den Einsatzbereich des erfindungsgemäßen Sappies weiter zu vergrößern, weist der Werkzeugschaft vorzugsweise wenigstens ein an seinem das Griffteil tragenden Schaftende ein Anreißmesser auf, wobei dem Anreißmesser eine im Griffteil ausgebildete Messerscheide zugeordnet ist. In diesem Fall dient der als Schiebeführung ausgebildete Werkzeugschaft dem wahlweisen Ein- und Ausfahren des Anreißmessers aus seiner Messerscheide.In order to increase the range of use of the invention further Sappies, the tool shank preferably at least one of its handle portion carrying the shaft end a Anreißmesser, wherein the Anreißmesser a formed in the handle portion sheath is assigned.
